@rui-ren The model gpt-5.3-codex is not available for your account. This can happen if the model was disabled by your organization's policy or if your Copilot plan doesn't include access to it.

You can try again without specifying a model (just @copilot) to use the default, or choose a different model from the model picker.

Pull request overview

Documentation update across the JS, Rust, C#, and C++ SDK READMEs adding a BCP-47 language-code reference table for the new Nemotron multilingual ASR model, plus a small C# cleanup that removes a Language field from the live transcription response type which the runtime no longer emits.

Changes:

• Add a "Multilingual Language Codes" section (table + short example) to the JS, Rust, C#, and C++ READMEs.
• Remove the Language property from LiveAudioTranscriptionResponse and its internal LiveAudioTranscriptionRaw in the C# SDK.

	audioClient.Settings.Language = "zh-CN"; // Chinese
	session.Settings.Language = "zh-CN"; // Chinese

[kunal-vaishnavi]

Suggested change

	audioClient.settings.language = 'zh-CN'; // Chinese
	session.settings.language = 'zh-CN'; // Chinese

[kunal-vaishnavi]

Suggested change

	audioClient.settings.language = 'auto'; // Auto-detect
	session.settings.language = 'auto'; // Auto-detect

[kunal-vaishnavi]

Let's change this code section to the following.

session.settings.language = Some("zh-CN".into()); // Chinese (Simplified)
session.settings.language = Some("auto".into());  // Auto-detect language

[kunal-vaishnavi]

Can we move these sections into the READMEs for the live audio transcription samples? These sections are currently listed in the SDK READMEs, which a customer will likely not see.
